Man goes to doctor and says he has a penis problem. The doctor asks him about his sex life. "I make love when I wake up, once after breakfast, come home for a quickie during my morning break, make love before and after lunch, come home for a quickie in my afternoon break, make love before and after tea, go to bed about 9.00 pm and spend the time to midnight making love".

When the doctor tells him he doesn't seem to have a penis problem he tells the doctor, "But it hurts when I wank".
